Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55812, here are decompositions:
- 5 + 55807 = 55812
- 13 + 55799 = 55812
- 19 + 55793 = 55812
- 79 + 55733 = 55812
- 101 + 55711 = 55812
- 131 + 55681 = 55812
- 139 + 55673 = 55812
- 149 + 55663 = 55812
Showing the first eight; more decompositions exist.
